I have only seen models in this range from 1960, going by case and movement numbers.
I have only seen a handful of any of the models, and only one collector who has all six models!

This is Lisa from West Virginia, a good friend of mine until she dropped off the radar.
Her collection numbers over 1,000 with a couple of hundred not added to her site.
Have a look around her site, you will not be disappointed!
